IL5851

The IL5851 is a monolithic CMOS integrated circuit which uses an

inexpensive RC oscillator for its frequency reference and provides all the

features required for implementing a pulse dialer with 32 digit redial.

• Wide operating voltage range (2.0~6.0V)

• Low power dissipation

• Use either a standard 2 of 7 matrix keyboard with negative true common

or the inexpensive form A-type keyboard

• Make/Break ratio can be selected

• Redial with * or #

• Continuous MUTE

• Power up clear circuitry on chip

• 10 pps/20 pps can be selected
